Depends on your state and the counties your agency/ies cover. To be continously busy, you will have to register with more than one, upgrade your skills and learn to market yourself. Where I am, the need for skilled in home care nursing is enormous. If willing, you can clock 60-70 hours weekly. Client needs surpass the number of nurses agencies can provide, and sadly some kids end up without a nurse when they desparately need one.
There's definitely $$$ to be made in PDN if you avail yourself and remain flexible.
Also school districts have been contracting with PDN agencies to staff their "special classes" with kids of medical needs like G-Tubes, Resp issues, etc. The most need is in large, urban inner city areas. Talking, networking with other nurses really helps in getting to know opportunities out there.
